Abstract

The present invention relates to a method for drying a wet raw material such as coal charged into a coke furnace through introducing a high temperature gas to a fluidized bed dryer as a heat source and a fluidizing gas, wherein a part of the above high temperature gas is blown into the inside of a charging chute for charging the wet material to the fluidized bed dryer. The above method can prevent the wet raw material from attaching to or depositing on the charging chute, at a low cost and with a simple process.
